TANKCAP AND LOCK.

Application filed May 21, 1927. Serial, No. 193,303.

The object-of this invention is the provision of a cap for the gasolinefiller tanks of automobiles which can be locked on the inlet spout forthe tank to prevent the surreptitious removal of gasoline from the tank.

A further object is the provision of a cap for this purpose which is ofa construction to establish a fluid tight joint between; the cap and thefiller spout of agasoline tank and which is further formed with a hollowlug for the barrel of a tumbler lock, and further wherein the boltmember of the lock is removably attached to the barrel so that differentsizes of such members may be employed to effectively engage the innersurfaces of tanks for different lengths of filler spouts.

To the attainment of the foregoing, the improvement consists in theconstruction, combination and operative arrangement of parts, asatisfactory embodiment of which is disclosed by the accompanyingdrawings.

In the drawings:

Figure 1 is a detail sectional view through a gasoline tank forautomobiles showing my improved cap arranged and locked on the spoutthereof.

Figure 2 is a bottom plan view of the. cap. Fi ure 3 is a perspectiveview of the bolt mem er for the lock.

Referring now to the drawings in detail,

the numeral 1 designates a filler or gasoline supply tank of the't-ype'which is attached to automobiles. The tank'l is provided with theusual inlet opening at the top thereof and thisopening is surrounded byan upstanding drawings. Of course, when the cap is to be annular flange2, that generally is termed a filler spout.

My improvement comprises a disc member 3 having on what I will term itsinner face, to an outer depending annular flange 4: and an inner annularflange 5. The flanges 4 and 5 receive the spout 2 therebetween. Arrangedon the inner wall of the cap, between" the flanges 4 and 5 there is acompressible disc ,6 which, of course, contacts with the outer edge ofthe s out 2.

integrally ormed with the cap, and with, the inner wall of the innerflange 5 there is a lug 7. This lug has a central opening therethroughfor the reception of abarrel 8.

The barrel is of the type usually employed in connection with pintumbler locks and has openings therethrough for the reception of shortpins 9 that are contacted by the spring influenced tumbler pins 10.These last mentioned pins 10 are received through suitable transverseopenings in the boss 7 The inner portion of the boss is reduced and isof a substantially rectangular formation as indicated by the numeral 11.It is through these 0 openings that the tumbler pins are arranged. Theinner wall of the part 11 of the boss is depressed transversely and inthis depression there is seated a plate 12 that closes the openings forthe tumbler ,pins and against as which plate the springs 13 for thetumbler pins contact.

' The belt member of the lock includes a disc head 14 and a bit portion15. The bit has an angular extension 16 and the sides of the to body ofthe bit are grooved, as at 17. These grooves are in a line with openin s18 in the head or disc 14 of the bolt, and t e openings receivetherethrough screws 19 whose shanks engage with threaded openings in thebarrel 8. The grooves permit of a screw 'driver readily engaging thekerfed heads of the screws 19. By this arrangement it will be seen thatdifferent size bolts maybe at-.

tached to the barrel so that the ca-pmay be $0 successfully employedupon tanks having different lengths of filler spouts 2. 'When the barrelis operated by the key 20 the bolt will be turned with the barrel sothat its bit 16 will be brought against the inner wall of w the tank, asdisclos'edlby Figure l of the removed the barrel is again turned but inadifferent direction to bring the bit to the dotted line position inFigure 1 of the drawmy mgs.

j The construction is comparatively simple and the advantages thereofare well known and will be appreciated by those skilled in the art towhic the invention relates.

Having described the invention, I claim Acap designed to provide a coverfor thefiller spout of a gasoline tank or the like said cap having on.one ofits'faces space annular flanges designed to receive therehem tweenthe spout, the inner flange being integrally formed with an enlargementthat is fluenced means for holding the revo ublevmember from turning anda removable plate seated in the enlarged portion of the inner flange forretaining said spring influenced 10 means in said portion of the flange.

In testimony whereof I aflix my signature.
